30202 Tapered cov menyuam bearings, ib kab
Cov yam ntxwv ntawm Tapered roller bearings
1. Kev sib txhuam qis
Lub optimized roller kawg tsim thiab nto tiav ntawm flange txhawb lubricant zaj duab xis tsim, uas ua rau muaj kev sib txhuam qis. Qhov no kuj txo cov kev sib txhuam kub thiab flange hnav.
2. Txhim kho kev ua haujlwm kev ntseeg siab
Optimized nto tiav ntawm qhov chaw sib cuag ntawm cov chais thiab raceways txhawb kev tsim ntawm hydrodynamic lubricant zaj duab xis.
3.Consistency ntawm cov menyuam profiles thiab qhov ntau thiab tsawg
Qhov ntev thiab geometrical kam rau ua rau cov tapered menyuam bearings yog xyaum zoo tib yam. Qhov no muab qhov zoo tshaj plaws load faib, txo cov suab nrov thiab kev co, thiab ua kom preload teem kom raug ntau dua.
4.Rigid bearing daim ntawv thov
Ib kab ib kab tapered rau cov menyuam kabmob feem ntau yog kho raws li qhov thib ob tapered cov menyuam kabmob. Los ntawm kev siv lub preload, ib daim ntawv thov kev coj tus kheej tuaj yeem ua tiav.
5. Sib cais
Lub nplhaib puab nrog rau cov menyuam thiab lub tawb sib dhos (cone) tuaj yeem ntsia tau sib cais los ntawm lub nplhaib sab nraud (khob).
